"Truer words were never spoken." My OP1 has worked perfectly since day one, thanks to Cyanogen Mod and a surprisingly good battery, which today holds it's charge for as long as it did on the day I received it. (Less than a 2-3% loss overnight.).

Every morning when I pick it up, that old saying comes to mind...... "They don't mak'em like they used to."
I anticipate this A0001 will well serve my needs, until a fully-operational 5G device becomes available in 2-3 years.
